Title: Current detector
Inventor: SATO TAKESHI
IPC: G01R33/06
Filed: 1991-01-28
Abstract: PURPOSE:To increase the capacity of noise resistance and enhance the accuracy of current detection by disposing a core on the pattern of a line for feeding electricity to an magneto-electric converting element provided on a printed substrate, the core being adapted to guide magnetic fluxes generated by currents to be detected. CONSTITUTION:A core 12 is disposed on the insulated pattern of a negative power supply line 15 serving as a power supply line for feeding electricity to the hole element 13 of a printed substrate 21 at which the lowest electric potential on a circuit is obtained. The surface of the pattern disposed on the substrate 21 is subjected to insulation processing except a connection terminal surface. Then the floating electrostatic capacity between the core 12 and the line 15 is increased as compared to other floating electrostatic capacities. Therefore, most of induced currents caused to flow from a wire 2 to the core 12 by the floating electrostatic capacity between the wire 2 through which a current to be detected flows and the core 12 is made to flow toward the earth side of a dc power supply 31 via the line 15 and a connector 30. Since the impedance between the power supply 31 and the earth is small, induced currents caused by other floating electrostatic capacities are decreased and the accuracy of detection of a current detector 1 is enhanced.

Inventor: TANAKA TAKASHI
IPC: H01R43/048
Filed: 1988-02-09
Abstract: PURPOSE:To shorten manufacturing time and to reduce cost by executing simultaneously pressing and welding by using a pair of metallic terminals connected in the head part of the opposite side of the fixing part, and a long-sized wire. CONSTITUTION:A pair of metallic terminals in which metallic terminals 2, 2' having an engaging hole are connected and formed integrally through a cutting part 3 in the head part of the opposite side of fixing parts 2-1, 2'-1, and a continuous long-sized wire are used. Subsequently, the wire 1 is pinched between the fixing parts 2-1, 2'-1 of the metallic terminals 2, 2', and the fixing parts are bent and brought to pressing, and brought to spot welding. Therefore, by the bent surfaces of the fixing parts 2-1, 2'-1 of the metallic terminals, the wire 1 is pinched, and welded with each other, and the wire 1 is brought to pressing and held surely. Accordingly, since the charge wire of a prescribed dimension is formed automatically, variance is eliminated from a product, and also, the production can be executed continuously. In such a way, the manufacturing time per unit is shortened and the cost of the product can be reduced.

Title: Manufacture of transformer
Inventor: MURAYAMA TAKESHI
IPC: H01F41/00
Filed: 1980-03-06
Abstract: PURPOSE:To prevent the humming sound by a method wherein a space as a source of producing the humming sound is freely filled up with a spacer made of thermo- restitutive resin which is heated during impregnating and drying processes. CONSTITUTION:Humming sound is produced by the vibration of a hum-proof belt 5 when there is a space between an iron core 3 and the belt 5. A spacer 7 is made of thermo-restitutive resin such as polyethylene resin, silicon resin, etc., and a space between the hum-proof belt 5 and the iron core 3 is filled up with resin, then the spacer 7 is heated at the temperature near a softening point. The resin spreads over the large or small residual space, and it is hardened after restitution, and free from deformation, so that it can fill up the space. As a result, humming is prevented without difficulty in processing as is often seen in press-boards, thus improving workability.

Title: Planarization of coating insulating film
Inventor: SATO JUNICHI
IPC: H01L21/3205
Filed: 1995-02-16
Abstract: PURPOSE: To provide a simple and secure technique for removing thick portions of peripheral portions of a coating insulating film made of SOG and the like. CONSTITUTION: An organic polymer layer 7 is formed on a coating insulating film 6, and peripheral portions of the organic polymer layer 7 are removed by an edge bead remover. Using the organic polymer layer 7 as a mask, the coating insulating film 6 is etched. On this stage, constant-velocity etch back may be performed on the organic polymer layer 7 and the coating insulating film 6. Also, heat treatment may be performed on the coating insulating film so as to make the film inorganic and fine, after the organic polymer layer is rotally removed. Thus, as the peripheral portions of the organic polymer layer are removed by the edge bend remover, the technique for removal is very simple without employing lithography. Since peripheral thick portions of the coating insulating film are removed by etching, these portions can be securely removed.

Title: Ultrasonic cultivation process
Inventor: HONDA KEISUKE
IPC: A01G7/06
Filed: 1993-01-25
Abstract: PURPOSE:To provide an ultrasonic culture process to grow a growing point of a plant by ultrasonic oscillation. CONSTITUTION:An agar medium 2 is put into a vessel 1, a growing point 3 of a plant is placed on the agar medium 2, an ultrasonic oscillator 4 is attached to the bottom of the vessel 1 and an output of an oscillator 5 is applied to the ultrasonic oscillator 4. Ultrasonic oscillation is applied to the growing point 3 from the ultrasonic oscillator 4 through the agar medium 2 by the application of oscillation output to the ultrasonic oscillator 4. Since the ultrasonic wave applied to the growing point has low energy, the growing point is subjected to the ultrasonic oscillation without deteriorating the quality of the agar medium 2 and, accordingly, the growth of the growing point 3 is promoted compared with a growing point 3 free from the application of ultrasonic oscillation.
